Silent Valley Reservoir, nestled in the Mourne Mountains, is a peaceful retreat surrounded by sweeping granite peaks and heathered slopes. Built in the early 20th century to supply water to Belfast and much of County Down, the reservoir combines striking engineering with natural beauty. Visitors can stroll along well-kept paths, admire the Victorian-style dam and impressive Mourne Wall, or simply enjoy the quiet atmosphere by the lakeshore.

The well-maintained trails take you through impressive scenery, surrounded by the striking peaks of the Mournes. The view of the Mourne Wall, which stretches for 35 kilometers and connects 15 peaks, is particularly impressive. However, some sections can become slippery in wet weather, so caution is advised. A highlight is a visit to Ben Crom Reservoir, which can be reached via an extension of the route. Note that there is a fee to enter the park.

The Long Woman's Grave car park is right at the top of a gentle climb, giving you the perfect opportunity to take in the rolling landscape. Whether you're coming from the north or the south, the roads take you through varied terrain that reveals new panoramas with every bend. It's worth taking a moment to read the story of the "Long Woman" at the memorial - somehow this mystical atmosphere fits perfectly into the surroundings. On the way up, you hardly encounter any traffic, which allows you to fully concentrate on nature and your own line in the bends. The fresh breeze and the smell of damp grass add a little extra to the climb. But the roads are not always in the best condition - some sections do require attention, especially after a rain shower. Once you reach the summit, there is a small rest area, ideal for taking a quick breather and regaining strength for the next stage. A perfect spot to take a short break before continuing with renewed vigor.

The hike to the Cloghmór Stone feels like a journey through time. Over 10,000 years ago, the ice brought this massive granite block from Scotland here, and now, weighing an estimated 50 tons, it towers majestically over the landscape. But it's not just the geology that's fascinating - according to legend, it was the giant Finn McCool who threw this enormous stone over Carlingford Lough. To be honest, the legend is a much more exciting explanation, isn't it? Once you've reached the top, you'll not only be greeted by the imposing boulder, but also by a fantastic view of Carlingford Lough and the surrounding hills. It's the perfect place to pause for a moment, take in the vastness and enjoy the peace that this place exudes.

A beautiful secluded clearing in the Oak forest. The message on the bench is pretty apt for any trail runners who have slogged up the hill!

Additionally, the Silent Valley Reservoir presents a tranquil lake setting amidst the Mourne Mountains, combining striking engineering with natural beauty.
Kilfeaghan is renowned for its ancient history, particularly the Kilfeaghan Dolmen, also known as "The Big Fella." This spectacular portal tomb dates back over 5000 years to the Neolithic period and is one of Ireland's largest dolmens. Its massive 35-40 ton capstone is a testament to ancient engineering. While primarily a man-made structure, its integration with the landscape and the surrounding natural beauty makes it a significant historical natural monument.

The Kilfeaghan area stands out due to its unique blend of ancient human history and diverse natural landscapes.

This ASSI is characterized by rare habitats including heathland, blanket bog, and grasslands, supporting unique flora and fauna. The presence of both colossal glacial erratics and ancient burial sites within a rich natural setting makes the area particularly distinctive.
The geology around Kilfeaghan is quite fascinating. The area features granites formed approximately 56 million years ago, as well as metamorphosed Silurian country rock known as hornfels, which exhibits distinct color banding.
